Solution 2

Try:

Image i = Image.FromFile(@"F:\Temp\MyPic.tif");
Image cropped = new Bitmap(200, 200);
Graphics g = Graphics.FromImage(cropped);
Rectangle dest = new Rectangle(new Point(0, 0), cropped.Size);
Rectangle source = new Rectangle(new Point(100,100), cropped.Size);
g.DrawImage(i, dest, source, GraphicsUnit.Pixel);
g.Dispose();

How are you showing the image in your web page?

I am using the ScriptManager to display the image as below:

string PDFfileName = string.Empty;
PDFfileName = txtImgPathHid.Text.ToString();
int MyRandomNumber = RandomNo.Next();
ScriptManager.RegisterStartupScript(this, typeof(string), MyRandomNumber.ToString(), "javascript:setsrc('" + PDFfileName + "');", true);
